A knockout mouse is a genetically engineered mouse in which researchers have inactivated, or knocked out, an existing gene by replacing it or disrupting it with an artificial piece of DNA.
(C) The selected heterozygous ES cells are inserted into the inner cell mass of a wild-type embryo, and the blastocyst is returned to the uterus. The resulting mouse is a chimera composed of heterozygous Bmp7 tissues and wild-type Bmp7 tissues.Mating the chimeric mouse to a wild-type mouse produces heterozygous Bmp7 offspring if the ES cells have contributed to the germ line.ere, the transgenic embryonic stem cells integrate with the hostâs embryonic stem cells. The embryo is placed into the uterus of a pregnant mouse, where it develops into a chimeric mouse. The chimeric mouse is then crossed with a wild-type mouse.
